 January, 1906, C. A. Ptirpus, no. L578 (type, in hb. Gray). This 



ractivc >]u'rii's of Eupatorium was submitted to tin 1 writer by Mr. 

 T. S. Brandegee. It approaches /:,'. prunettifolium 1 1 UK., but differs 

 in it- Blender flexuoiis proeiimheut stems, and more evenly and sharply 

 senate Leaves, which are essentially glabrous above. E. oligocephalum 

 DC, an imperfectly known species, may also be of this affinity ; hut it 

 is described as Laving glabrous involucral scales.

 marked Bpecies appears never to have been described. The plant in 

 question has been repeatedly distributed as Eupatorium vanillosmoides 

 Sch. Bip., but the Bpecies to which Schultz really gave this name was 

 a Brazilian plant of entirely different affinity, referred by Mr. Baker
